The R project is a free online statistical environment which allows users to import, analyze, and produce visual representations for data. R may be useful in a busy clinical environment to provide objective evidence of progress in physical therapy for clients and payers.


Demonstrate how R can efficiently document physical therapy outcomes to justify treatment to patients and third party payers.

Case Description.

Case 1: Functional Independence Measures, collected once a day for 48 days, were used in inpatient rehabilitation to track progress of bed mobility, transfers, wheelchair mobility, gait, and stairs.

Case 2: Alberta Infant Motor Scale, independent sitting and quadruped time recorded biweekly for 8 weeks utilized to tracking gross motor development in a typically developing infant.

Case 3: Knee passive range of motion and hop tests recorded once a week, while Landing Error Scoring System and Knee Outcome Survey scored every 6 weeks, to track a male for 6 months after an ACL reconstruction and meniscal repair.


For each case, R was used to create graphs that visually illustrate progress of each individual. These graphs include stacked line and scatter line plots to show change over time.


Basic statistical knowledge is a suggested prerequisite, however R is convenient once the program is downloaded and foundation in R basics is established.


R was successfully used to track patient progress in various types of Physical Therapy settings. R was helpful in visually demonstrating objective patient progress over time.
